WebYou can test this statistically for categorical data using the chi-square test for homogeneity. When your p-value is low, reject the null hypothesis (homogeneity) and conclude that the samples are heterogeneous. The differences between the category proportions are dissimilar enough to be statistically significant. http://sthda.com/english/articles/39-regression-model-diagnostics/161-linear-regression-assumptions-and-diagnostics-in-r-essentials
